(a) A bathroom scale has a spring that is compressed by 1.50 cm when a 165 kg person stands on the scale. Assuming the spring is described by Hooke's law, find its force constant.
(b) How much would it be compressed if a 94.0 kg person stands on the scale in an elevator that is accelerating upward at 1.25 m/s2?
k= mg/Δx =165/0.015 = 11000 N/m
